I think "yes". What inverter did you use? The one that belonged with the panel or the cable?

i tried to boot non-ibm panel without inverter connected to them, it gets power up, power down, and thats all, after that he don't power up with oryginal panel and inverter.

Try to reset it by unplugging it and removing the battery. Pust the power button several times (about 10) holding it for 5 seconds the last time.

this not helping,

after removing battery, and pluging them back laptop starts only once after pushing power button, then he power off, and no reaction at all on power button

laptop has gone to hw service.

however for anyone intrested:
ever try attach TX36D98VC1CAB or compatible to your thinkpad, it will fry motherboard or just lcd controller chip (dude from service confirmed this to me), that's my lesson for this time

serious question, does LTN141P2-L02 will work with thinkpad?
anyone tried? results?

I had the impression that this question was already asked in your other thread: T40 lcd replacement - was the answer posted there perhaps incorrect?? If indeed so, you ought to update that thread, I suggest. Check the last post in the thread T4x LCD replacement issue - did user Msmax get this to work?

The following advertisement: Samsung LTN141P4-L02 14.1 Inch Laptop LCD Screen SXGA+ 1400X1050 seems to indicate that the answer to your question is "yes"...

Best regards,

Johan

I think he didn't use the SXGA+ cable, that may be the reason he killed the mobo.

The only thing that would change is the resolution. It either wouldn't send data to the screen or it would run at 1024.

Hi All,

First I fried my mainboard using the LTN141P2-L01 screen from Samsung.
Then I purchased a new mainboard from the marketplace here and used the LTN141P4-L02 screen of Samsung which works fine.

Notebook has been sold now a long time ago, but still works fine.

I'm asking about LTN141P2-L02 not, LTN141P4-L02.
They are the same ?
